1 Overview

The TAS5715EVM evaluation module demonstrates the TAS5715 device from Texas Instruments. The

TAS5715 combines a high-performance PWM processor with a class-D audio power amplifier. This EVM

can be configured with two bridge-tied loads (BTL) (2.0). For detailed information about the TAS5715EVM

device, review the (device data sheet SLOS645). The Pulse Width Modulator (PWM) is based on TI's

Equibit™ technology. The TAS5715 has additional audio processing features like 3D, Bass Boost and

2-band DRC.

The EVM software, with its graphic user interface (GUI), facilitates evaluation by providing access to the

TAS5715EVM registers through a USB port. See the Using the EVM Software section for further details.

The EVM together with other TI components on this board, is a complete 2.1-channel digital audio

amplifier system. The MC57XXPSIA Controller board includes a USB interface, a digital input (SPDIF),

analog inputs via the ADC, power inputs, and other features such as a mute function and power down.
